DETAILED DESCRIPTION

While this invention is susceptible of an embodiment in many different forms, there are shown in the drawings and will be described herein in detail specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention. It is not intended to limit the invention to the specific illustrated embodiments.

Embodiments disclosed herein can include systems and methods for dynamic output control hierarchy for wireless fire systems and for fire protection before and during the installation thereof. For example, in some embodiments, dynamic output control hierarchy can be based upon the failure of components of the wireless fire system. Additionally or alternatively, in some embodiments, a hybrid device of the wireless fire system can be self-activated when predetermined conditions are detected, for example, when the hybrid device determines that the wireless fire system or a gateway device thereof is jammed. Additionally or alternatively, in some embodiments, systems and methods disclosed herein can provide fire protection and annunciation capabilities before and during the installation and wiring of a fire system control panel. Additionally or alternatively, in some embodiments, systems and methods disclosed herein can provide fire protection when a fire system control panel or a loop card fails. Additionally or alternatively, in some embodiments, systems and methods disclosed herein can provide fire protection when communication with an SLC controller fails.

In accordance with disclosed embodiments, a wireless fire system can include a fire system control panel, a gateway device, and a mesh network. In some embodiments, when the mesh network loses communication with the fire system control panel, the gateway device can control activation of its own output devices and output devices in the mesh network. Additionally or alternatively, when the gateway device fails, one of the wireless devices of the mesh network can act as a gateway device by controlling wireless output devices in the mesh network. Additionally or alternatively, when the gateway device fails, a hybrid device of the mesh network can control activation of its own output devices based on the activation of input devices attached to the hybrid device.

For example, a hybrid device that is part of a mesh network can be battery powered and can be an input and output device, such as, for example, a wireless sounder device. During normal operation, the hybrid device can operate under the control of the fire system control panel. However, when the hybrid device determines that the wireless fire system or the gateway device is jammed, the hybrid device can drop out of the mesh network and be self-controlled and self-activated based on ambient conditions, such as heat or smoke, detected by its input devices.

FIG. 1 is a flow diagram of a method 100 in accordance with disclosed embodiments. As seen in FIG. 1, the method 100 can include determining whether a fire system control panel has failed as in 110. When there is no fire system control panel failure, the method 100 can include the fire system control panel controlling and activating wired and wireless output devices in a fire system that are coupled thereto as in 120.

However, when the method 100 determines that the fire system control panel has failed as in 110, the method 100 can include a gateway device controlling and activating wireless output devices in a wireless fire system coupled thereto as in 130. Then, the method 100 can include determining whether the gateway device has failed or the wireless fire system is jammed as in 140. If not, then the gateway device can continue controlling and activating the wireless output devices in the wireless fire system as in 130.

However, when the method 100 determines that the gateway device has failed or the wireless fire system is jammed as in 140, the method 100 can determine whether another device in the wireless fire system is configured to take over for the gateway device as in 150. If so, then the method 100 can include the other device in the wireless fire system that is configured to take over for the gateway device controlling and activating the wireless output devices in the wireless fire system as in 160. However, when the method 100 determines that no other device in the wireless fire system is configured to take over for the gateway device as in 150, then the method 100 can include a device in the wireless fire system, such as, for example, a hybrid device or a sounder device, self-controlling and self-activating its own output devices as in 170.

In accordance with the above and a first example of embodiments disclosed herein, when a gateway device loses communication with a fire system control panel or when the fire system control panel fails, the gateway device can detect the communication loss or the control panel failure and, responsive thereto, begin controlling output devices in the mesh network coupled to the gateway device. For example, in some embodiments, the gateway device can be preconfigured with instructions stored in memory and activate some or all of the output devices in the mesh network based on those preconfigured instructions. Furthermore, in some embodiments, the gateway device can synchronize all of the output devices in the mesh network.

In accordance with the above and a second example of embodiments disclosed herein, when a gateway device fails, a battery powered hybrid device, such as, for example, a sounder device, can detect the gateway device failure and, responsive thereto, begin self-controlling and self-activating its own output devices based on ambient conditions, such as, for example, heat or smoke, detected by its own input devices.

In accordance with the above and a third example of embodiments disclosed herein, when a gateway device fails, another wireless device in a mesh network can detect the gateway device failure and, responsive thereto, begin controlling and activating other output devices in the mesh network.

As explained above, in some embodiments, systems and methods disclosed herein can provide fire protection and annunciation capabilities before and during the installation and wiring of a fire system control panel. For example, a hybrid device, such as, for example, a sounder device, can be installed outside of a fire system network and in locations that are prone to fire and can provide fire annunciation independently of any signals from or connection to a fire system control panel, for example, by providing fire annunciation responsive to ambient conditions, such as, for example, heat or smoke, detected by its own input devices. However, when the fire system control panel or a gateway device becomes available and coupled to the hybrid device, the hybrid device can receive control signals from the fire system control panel or the gateway device for fire annunciation.

FIG. 2 and FIG. 3 are block diagrams of a system 200 in accordance with disclosed embodiments during normal operation. As seen in FIG. 2 and FIG. 3, the system 200 can include a fire system control panel 210, a gateway device 220, a plurality of mesh network devices 230, and a hybrid device 240. During normal operation and as seen in FIG. 2, the control panel 210 can transmit a signal to the gateway device 220 for activation of the hybrid device 240, and the gateway device 220 can transmit the signal to the hybrid device 240 for activation of the hybrid device 240 via one or more mesh network devices 230. Also during normal operation and as seen in FIG. 3, the hybrid device 240 can transmit a signal with an alarm message to the gateway device 220 via one or more mesh network devices 230, and the gateway device 220 can transmit the signal with the alarm message to the control panel 210.

FIG. 4 is a block diagram of the system 200 in accordance with disclosed embodiments during a self-control and self-activation mode. As seen in FIG. 4 and as explained above, when the hybrid device 240 detects predetermined conditions, when the hybrid device 240 determines that the system 200 or the gateway device 220 is jammed, when the hybrid device 240 determines that the gateway device 220 has failed, or when the hybrid device 240 determines that the gateway device 220 has failed and none of the mesh network devices 230 is configured to take over for the gateway device 220, the hybrid device 240 can begin operating in a self-control and self-activation mode. For example, the self-control and self-activation mode can include the hybrid device 240 controlling activation of its own output devices based on activation of its own input devices attached to the hybrid device 240, such as an input device of the hybrid device 240 detecting an ambient condition, such as, for example, heat or smoke. In some embodiments, the self-control and self-activation mode can include the hybrid device 240 dropping out of a mesh network with the mesh network devices 230.

Each of the fire system control panel 210, the gateway device 220, the mesh network devices 230, and the hybrid device 240 can include a transceiver device and a memory device, each of which can be in communication with respective control circuitry, one or more programmable processors, and executable control software as would be understood by one of ordinary skill in the art. The executable control software can be stored on a transitory or non-transitory computer readable medium, including, but not limited to, local computer memory, RAM, optical storage media, magnetic storage media, flash memory, and the like. In some embodiments, some or all of the control circuitry, the programmable processors, and the control software can execute and control at least some of the methods described above.

Although a few embodiments have been described in detail above, other modifications are possible. For example, the logic flows described above do not require the particular order described or sequential order to achieve desirable results. Other steps may be provided, steps may be eliminated from the described flows, and other components may be added to or removed from the described systems. Other embodiments may be within the scope of the invention.

From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the invention. It is to be understood that no limitation with respect to the specific system or method described herein is intended or should be inferred. It is, of course, intended to cover all such modifications as fall within the spirit and scope of the invention.
